Enormnn WHEEL i Application ld August 15, 1927. .Serial No. 212,978'.

This invention relates to wheels, and is .illustrated as embodied in oneof the wheels of an aeroplane. An object ofthe invention is to provide avery strong lwheel which is dished in such a manner as to permit thearrangement, in the load plane of the wheel, of a device for absorbingthe shock of landing.

In one desirable arrangement, the wheel includes two disks having acentral hub proa jecting away from the load plane at the center of thewheel.` lPreferably the wheel has a rim, for example of the drop-centertype', to which the disks are secured yat their outer edges. One of thedisks,shown as the inner one, is secured'to the other disk in a plane`spaced outwardly from the load plane, is then dished inwardly,preferably in such a manner as to engage the bottom of the drop centeroli' the rim, and finally is secured to the opposite side Aof the rim'.

The above and other objects and eaturesof the invention, includingvarious novel combinations of parts and desirable particularconstructions, will be apparent from the follow- Y ing' description of'.one illustrative embodiment sshown in the accompanying drawing, inwhich:

The figure .is a vertical central section through theV wheel and itssupport.

The particular wheel selected for illustra-` tion includes an outer tirerim 10, shown as having;r a drop center 12, and a central tubular hub 14rotatably mounted' on a bearing;r on a spindle 16 which` with the hub14, projects outwardly away from the load plane ci the wheel. Spindle'lmay, ifdesired,

be integral with a cylinder 18 forming part.

et the means for alzisorbinpfl the shockof landing. y c

Hub i4 is confined endwise between cyliuder 'i8 and a ring 2O held by across pin or the like The shock absorber also in cludesa piston 24 inthe cylinder 18, the piston being' carried by a part 2G secured to theaeroplane proper and corresponding` generallv to an axle. The shockabsorber is more ."iully described and is'elaimed in our co-pendning'application No. 212,974, filed August 15, T92 i Y Y The body of thewheel preferably comprises two disks 28 and 30 secured, by rivets orthe; like 32, to opposite sides of a lange 34 extendin voutwardly fromhub 14. Disk 28 is forme at its outer edge with a flange. 36underlapping the outer side flange of rim and secured theretoby meanssuch as rivets 38, passing through blocks 40.

Disk is secured to disk 28, just inside the rim, by meanssuch as rivets42, and is then dished inwardly, thus bringing the shock absorber 18-24substantially in the load plane of the wheel. The disk `30 engages, andpreferably is secured by rivets 44 or the like, to the bottom of thedrop center 12 of the rim, and finally is formed with a flange 46undervlapping; the side flange of rim 10 opposite the disk 28, andsecured thereto by means such as rivets 48 passing through blocks 50.

When it is desired to provide a brake engagingthe inside of the dishedportion of disk 30, the rivets 44 are omitted.

We prefer to make most or all of the aboveL y described parts ofrelatively light material .limit the scope of theinvention to thatparticular embodiment, or otherwisethan by the terms of the appendedclaims.

We claim:

1. A wheel comprising, in combination, a rim havingr adrop center, a hubat one side of the plane of one side of the rim, and a pair ofl diskssecured to said hub, one of the disks being secured at its edge to theouter side of the rim, and the second disk being secured to the firstdisk just inside the rim and thencel dished toward the inner side of thewheel and engaging the bottom of the drop center of the rimv and finallysecured to the side of the rim opposite the first disk. substantiallyall of the space within the rim being left unobstructed by the hub anddisks. K

2. A wheel comprising, in combination, a rim having a drop center, andtwo disks secured to each other inside of the circle of the rim, thedisks beingr secured to the opposite sides of the rim and one of thedisks being dished across the load plane of the wheel and engaging thebottom of the drop center of the rim in the load plane of the Wheel.

3. A Wheel comprising a rim provided with a drop center portion,together with a Wheel body part secured to one 'side of the rim, saidbody part being arranged to cross the load plane of the Wheel and beingsecured to said drop center portion in the load plane of the Wheel, saidbody part being spaced from the wall of said rim between said securedpoints so as to serve as av strut for the side of said rim.

In testimony whereof, We have hereunto signed our names.
